PCB的静电容分析Application Report SBOA094 - August 2003 Measuring Board Parasitics in High-Speed Analog Design Rea Schmid ABSTRACT Successful circuit designs using highspeed amplifiers can depend upon understanding and identifying parasitic printed circuit board (PCB) components. Simulating a design while including PCB parasitics can protect against unpleasant production surprises. This application report discusses an easy method for measuring parasitic components in a prototype or final PC board design by using a standard oscilloscope and low frequency waveform generator to collect valuable information for SPICE simulation.
